For these you need minimum of 256mb ram. But the virtual Memory size usually it?s the double of RAM, so in your case 256mb. It?s definitely low. One solution to increase this from System Properties->Advanced->Perforamce->Settings->Advanced->Virtual Memory->Change. My advice is to change the value to min.1024mb. Good luck!

You can increase your pagefile (Performance Options under Advanced Tab in System Properties) provided you still have enough available HD space. That being said you should also try to always have enough free space on your partition, this allows disk defrag to run properly. The old rule was 25%, but if your using a large HD (80GB plus) 25% isn't really needed & you could go with 20% on a 80GB, 15% on a 100GB & so on.....I wouldn't go less than 10% free space on anything larger than 120GB.

I wouldn't worry to much about increasing your pagefile & stick with upgrading your RAM 1st & formost. With only 128MB of RAM increasing your pagefile may solve the low virtual memory problem but your systems performance will be further degraded, by the sounds of it that PC is likely running pretty slow & you probably don't even realize it.

Since I don't know what MB you have I'll just say to add 512MB of RAM & simply leave the 128MB dimm out of the picture on the basis of compatibility issues. I'd also stick with a name brand of RAM like Kingston, Corsair, Ocz tech or Crucial.

If you upgrade your RAM just let Windows manage your pagefile, XP does a decent job of it.

Also, you may want to recall that compatibility issues exist between with JAVA and MS Windows. One commen observation is that JAVA apps (such as Tomcat) experience memory leak on the Windows platform when no memory leak is observed running the same software in the *nix environment. Scheduling frequent reboots of your Windows server will help release memory.
